Specification of Letters Patent.

Patented July 23, 1918.

Application filed March 19, 1918. Serial No. 223,361.

To all whom it may concern:

Be it known that I, BERNARD EELHART, a citizen of the Netherlands,residing at Holland. Michigan, have invented certain new and usefulImprovements in Heat-Disseminators, of which the following is aspecification.

This invention relates to devices for distributing the heat coming fromregisters of hot air heating systems. The invention is in effect aradiator although this term should not be confused with a radiator of ahot water or steam heating system. The object of the invention is toproduce a device that will more efliciently disseminate the heat comingfrom a register and at the same time free the hot air coming from theregister of all dust.

The invention is illustrated in the accomp:m \'ing' drawings in whichFigure 1 shows a side elevation of the device; Fig. 2 a verticallongitudinal section of the same, and Fig. 3 a transverse section of theradiator. Fig. 4 is a transverse section of a modified form and Fig. 5is a longitudinal section of the same. Fig. 6 shows a modification.

In the drawings, the numeral 11 indicates an ordinary register of a hotair heating plant already installed. My device consists of a portablerectangular casing adapted to be placed at random over any desiredregister. The device is supported on legs 12 and consists of a bottomopen ended drum 13 supported on the legs 12. This drum 13 is providedwith angle members 14: therearound on which an open bottomed drawer 15is adapted to rest. The drawer is provided with a plurality of fine meshscreens 16 or other dust catching devices and has a handle 17 on itsfront face 18 which projects through an opening 19 in the drum 13. Theupper portion of the drum 13 has a plurality of apertures 20 and insidethe drum, a damper slide 21 is provided having openings 22 adapted toregister with the openings 20. These slides 21 are held in runways 23.From the to of the drum 13 a downwardly curved deflector element 24 iscarried havingta restricted neck, and an open centered top 25 fits onthe top of the drum and deflector. which has a downwardly curved outsideguiding flange 26.

Upon the structure so far described, is placed an intcrmediate drum 33having apertures 40, damper 'slides41, openings 12, runways 43,deflector element 41, top 45, and guiding flange 46all as provided forthe drum-13. Supported uponthe top 45 is a crown 17 forming the top ofthe radiator.

In the operation of this device, the hot air from the register 11 inrising draws in some of the air from the room as is obvious. This mixedair passes through the screens 16 where it is freed from dust. Whenthese screens become filled with dust, the drawer 15 is removed from thedrum 13 of the radiator whereupon the screens may be cleaned.

Some of the cleansed heated air is deflected upwardly by the element 21so that it passes out through the openings 20, provided the dampers 21are open. and downwardly around the guides 26. The remaining hot airpasses upwardly through the restricted neck of the deflector 24 into theintermediate drum 33 where it is again subdivided, part going outthrough the openings 40 around the ouides 4:6 and part going up throughthe nech of the deflector 1 1. It continues to rise until it hits thecrown 47 whereupon its direction is reversed and the accumulation of theincoming air will cause this downwardly directed air to descend aroundthe edges of the neck of the deflector 41 whereupon it joins the airpassing through the openings 40.

In the modified form shown in Figs. 4 and .5, the intermediate drum 33and crown 47 ofthe device of Figs. 1 to 3 are removed and the drum 53and crown 57 substituted therefor. The principle of construction ofthese elements is the same as in Figs. 1 to 3, the only difference beingthat the drum 53 is equipped with an oven 58 supported on bars 59 orother supports. Access may be had to the oven by means of the door 59.

Fig. 6 shows a modified'form of my device in which 60 represents adamper for shutting off the heatfrom the register from rising into theradiator if this should be de-;

sired. 61 represents extensible frames adapted to be secured to theregister flange 5 for conducting the hot air direct from the re ister tothe radiator.

Vhat I claim is: 1. A radiator of the class described comprising aplurality of superposed. drums,-

drum, and a non-apertured crown surmounting'the top drum.

2. A radiator of the class described comprising a plurality ofsuperposedidrums, restricted deflecting necks inclosed by each 15 drum,downwardly curved guides outside the-drums forming a continuation of thedeflecting necks, and. a non-apertured crown surmounting the top drum.
